Suppliers, Traders, Exporters and Stockists of Stainless Steel Grade 316L Round Bars & SS Rods
ARK Stainless is a leading supplier, trader, stockist and exporter of 316L round bars and rods. The 316L Round Bars are made up of the low carbon version of the 316 grade stainless steel alloy. It has a maximum carbon content of only 0.03%, whereas it is 0.08% for the 316 grade ss.
The 316L ss round bars offers better corrosion resistance and is more suitable for high temperature applications. It also has better intergranular corrosion resistance. Due to all the physical properties that include superior weldability and higher resistance to corrosive chemicals, the Stainless Steel 316L Round Bars are widely used in pharmaceutical and food processing equipment. They are also used in architectural and marine applications.
The 316L Stainless Steel Rod is widely used for heavy gauge welding applications. This is because due to its chemical composition, the rod is less susceptible to decay. The low carbon content helps in decreasing the carbide precipitation which sensitizes the weld's grain boundaries in these materials.
AMS 5653 is the AMS number for SS 316L material. It is known by other specifications too, like UNS S31600. This is a heat resistant and corrosion resistant alloy, which is used for a wide range of applications across several industries. The low carbon content in the alloy improves its weldability and corrosion resisting properties.
The Turned, Ground and Polished procedure for the 316L round bars helps in converting a coarse and roughly dimensional 316 ss rod to a round bar with straight and smooth surfaces. The turning procedure ensures that the steel rod gets to the desired sizes. Multiple passes might be needed with the cutting tool depending on how big the rod is. This is followed by grounding and polishing, which helps to improve the surface condition of the round bars and improve its appearance. With the polishing process, the ss 316L bars gains a smooth and finished surface.
SS 316 Bars & Rods recognized for the property of more resistant to corrosion than any other alloys. It is recommended for a thermal process, pressure fittings, valves, flanges, and so on. It has the addition of molybdenum to resist pitting in chloride comprising atmosphere and to crevice corrosion. SS 316 Bars & Rods have a passive layer on the surface to resist corrosion attacks in water-based media or oxidizing environments. It is found in an appliance where salt and bleach present in the media, but it is not rust-proof and not suitable for welding.
SS 316L Bars & Rods appliance found in down to cryogenic temperature. It has excellent long-lasting durability and weldability. Its microstructure of nickel associated with chromium provides superior tensile strength, corrosion resistance, stress to rupture characteristics. SS 316 Bars & Rods is suitable for a water-based environment such as blackish and saline water, and it has a passive layer to resist crevice corrosion also. But, it is not recommended in media where it can expose to pitting corrosion.
The alteration of the chemistry for any stainless steel is appropriate for certain speciality operations. One such operation is the welding of 316L Steel Cold Finished Bars. Welding forms a permanent joint in a process based application. It involves the use of heat to melt or solder the product such that the JIS SUS 316L black bar is easily connected to a system. In instances where the content of carbon is really high, there is a formation of carbide precipitation at the grain boundary of these components.
Thus, leading to decay or intergranular corrosion. Also since the presence of high carbon in a product inhibits the formation of good welds. This is because carbon is chemically stable, even at high temperature, which in entirety defeats the purpose of welding. Hence suppliers suggest using 316L stainless steel round bar, as the lower content of carbon discourages carbide precipitation and unlike 316H, it eases welding operation. In addition to easing the process, using 316L stainless steel rods speeds up the joining operation, making it an asset to manufacturers. Typically, most individuals associate 316L stainless steel welding rod with marine grade. And, hence, they often use these bars in marine engineering. Furthermore, the ASTM A479 UNS S31603 hex bar functions well despite being exposed to seawater that contains halides or halogen elements such as Chlorine, fluorine and bromine.
The astm a276 type 316L flat bar is also non-toxic, making them useful additions in the pharma sector as well. Even the food industry, which has a high demand for sanitary products find using the DIN 1.4435 square bar an investment. Industries like pharma and food, frequently clean their equipment using harsh chemicals. Being a non-reactive allot, the ss 316L bright bar is perfect for these applications. Though the cost of using this alloy is much more than grade 304, the benefits offered by AISI 316L threaded bar outnumber grade 304.
